What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeThis study investigates the competence of a newly certified radiologist in reporting hydrops imaging and examines the role of magnetic resonance imaging (MRI) findings in diagnosing definite and probable Ménière's disease (MD).
methodsSixty-four cases were retrospectively evaluated-blinded to clinical data-by a senior radiologist (O-1) and a newly certified radiologist (O-2) using 3D heavily T2-weighted and delayed contrast-enhanced three-dimensional fluid-attenuated inversion recovery sequences. The posterior fossa-posterior semicircular canal (P-P) distance, endolymphatic hydrops (EH), perilymphatic enhancement (PE), and the round window sign (RWS) were assessed.
resultsInterobserver agreement was moderate for cochlear (κ = 0.591) and vestibular hydrops (κ = 0.566), good for PE (κ = 0.663), and excellent for the RWS (κ = 0.817). O-1 demonstrated good intraobserver agreement for the RWS (κ = 0.787) and excellent agreement for the other parameters. O-2 showed lower intraobserver agreement for cochlear hydrops, vestibular hydrops, and the RWS (κ = 0.366, κ = 0.332, and κ = 0.398, respectively). The P-P distance showed excellent interobserver [intraclass correlation coefficient (ICC) = 0.932] and intraobserver agreement (ICC = 0.978 for O-1; ICC = 0.886 for O-2). The P-P distance was significantly shorter in definite MD (dMD) than in probable MD (pMD) (1.23 ± 1.07 mm vs. 2.17 ± 1.79 mm,
conclusionThe newly certified radiologist's intraobserver agreement for hydrops imaging was insufficient. In dMD, the retrolabyrinthine bone is thinner, hydrops is more frequent and advanced, and the RWS is less common. Approximately one in five patients with MD may have a perilymphatic fistula. Close monitoring of asymptomatic contralateral ears is essential. CLINICAL SIGNIFICANCE: Accurate MRI evaluation of EH in MD strongly depends on the radiologist's expertise. This study highlights that newly certified radiologists may show lower reliability in assessing hydrops imaging, underscoring the need for targeted training programs.
